Rims on a deville - Best size and best style?

I've got a white 2000 Deville. If I was gonna put rims on it what size and style would you recomend. I'm thinking either 18's or 20's but I don't know if 20's would look to big and ugly on a deville or not. I've allready got a style of rims in mind but I'd like to hear your opinions too.
 
 

Try these on for size

I know it can get confusing when given too many choices but you should look at this.

what ever you get make sure you get vogue tyres.Believe me you wont regret it and you'll love your car much more. I would prefer a nice set of 18" chrome caddy rims

me personally i have had rims on my 2000 deville
i had 20 inch and 22 inch rims
believe it or not there was not that much ride quality lost between the 2
i purchased both from a store in miami called wheel and tire outlet
ask for mike if you wish to call....he has a deville also with 22inch rims
their number is 305-259-9411....he is good and he will tell you all the good and bad when putting rims on the deville
hope this helps

Thanks for the info.  I like to see people who have had good service let us know.  Tire shops, mechanic shops, mod shops, etc etc.

20's what the F is wrong with you dont ever say 18's and cadillac in the same sentence. Get you some 20's or 22's they would both look nice.

 
I am really going radical on the Caddy.  my 15's are coming off and I am going to 16's.
Now I really gotta be carefull with  them potholes.

What. everyone has 20's and 22's besides big rims are just played out already. Get some factory chrome 18's and vogues and you'll still have a nice comfortable ride and have a sharp classic(grown) look.

I really like the factory rims as they are, I don't know if it'd even be worth the money to buy new rims. If I do end up buying some they'll definetly be 20's though.
 
Anyone got pictures or links to rim styles you'd recomend for a Deville?
 

Theres a guy around my town with a deville on 26's and it looks rediculus and ugly he spent well over 6 grand on tires and rims so don't go bigger than 22's crome   look at HELO   Juices i have those on my deville its baller as **** 20's
